//You can do any of the following:
//Suppress candle or bar plotting
//Choose to plot candle or bar
//Show the Gann angle projections from Highs, Lows or Peaks and Troughs
//(the latter can be delayed in appearance because of the Amibroker fn limitation)
//Extend the Gann angle range by changing the Gann Range
// Current settings will work for scrips that are in the range of the Nifty
//Show the Angle number from 0 – 6. Useful for you to decide your trading rules.

I had a question: this code is made to fit more or less Nifty prices, as you well indicated in the code. When you use it on daily charts or for other symbols, it doesn’t plot.
Could you please indicate where in the code some constant needs to be changed? Thank you.
